Why do we use tiles for roofs instead of a smooth flat sheet?

144 viewsOther

Why roof tiles exist. I understand why we don’t have flat roofs, but why do we have hundreds of tiles that sort of overlap each other and can be pulled or blown off easily?

Why aren’t roofs like a giant tent, still A shaped but each side is just a big sheet of whatever weatherproof material we got?

I would imagine the history of roofing is something like:
– Leaves and Branches
– Thatch, which if you overlap it, works pretty well
– Wooden shingles, pretty cool but rot away / burn, so…
– Clay or slate tiles

The size of the tiles is going to be limited to what one guy up on a ladder can comfortably lay on his own.
